Rosalia Gallotti, Université Paul Valéry – Montpellier III More than 1.5 million years ago, a new era dawned for our human ancestors, Homo erectus: the Acheulean culture. This period was marked by the ability to produce large cutting tools, mainly handaxes, manufactured using different kinds of rocks and used for a variety of activities. These […]

Daniel Zadik, University of Leicester It is well established that modern humans originated in Africa, before moving out to inhabit rest of the planet. They first spread into Asia and Europe via the Arabian Peninsula, and those in the Far East eventually reached America and the Pacific islands. However, this simple picture does not explain

Elgidius Ichumbaki, University of Dar es Salaam and Marco Cherin, Università degli Studi di Perugia In 1976 paleoanthropologist Mary Leakey and other scientists reported that they’d found ancient hominin footprints at a site in Laetoli, northeastern Tanzania. The footprints were frozen in volcanic deposits from the Pliocene, an epoch that lasted from 5.333 million to

How did human beings become so successful at adapting to whatever environment we wind up in? Human origins researchers like me are interested in how this quintessential human trait, adaptability, evolved. At a site in Kenya, my colleagues and

Irene Esteban, University of the Witwatersrand and Paloma de la Peña Alonso, University of the Witwatersrand There is a fair amount of archaeological evidence that indicates complex behaviour among our ancestors. For instance, there are bone tools that were used as hunting projectiles, for working leather or for processing plants. Ochre remnants were used for

Darren Curnoe, UNSW Sydney A report published today in Nature by Yohannes Hailie-Selassie and co-workers outlines the importance to our evolutionary story of some very ancient foot bones discovered recently in the Rift Valley of northern Ethiopia. The findings matter because the beginnings of the human evolutionary line remain murky. We know that humans shared

Darren Curnoe, UNSW Sydney The origin of the human species remains one of the most fascinating and difficult topics of modern science. One of the main reasons for this is a continuing lack of agreement about how we should define ourselves. In other words, what is it that makes us human (or, scientifically, Homo sapiens)?
